Description
The QTerm functionality is provided in a java bean and as java applets.
The base functionality is common to the java bean and to the applets, which
support terminal emulation in a web browser. The java beans may be used in
a variety of implementations including servers and web services.
The java components provide the complete functionality of a terminal
connected over TCP/IP to a Unisys mainframe.
Applets
Please refer to the QTermJavaUTS and QTermJavaT27
product descriptions for the web browser implementations. A web server
page is accessed from a user's desktop to
automatically download the applet. The first access may involve
downloading of the java plug-in.
Beans
The java beans provide terminal connectivity, from which many instances may
be invoked. Such connections are typically used for host screen scraping
in server applications. As such the terminal "screen" is
normally hidden but may easily be made visible, for debug purposes.
QTermJava SDK
The primary objects are QScreenUTS and QScreenT27, each of which provides a
single instance of a terminal connection to the host.
The provided applets actually create one or more instances, depending on
how many terminal screens are required. If you write your own applet
or stand alone java program you would do something similar.
If you are programming a server application then you will create one or
more instances of the terminal object directly, using the classes from the
bean jar file.
Sample java code and html pages are included. For programming
interface details please see the JavaDoc.
Note that although you create a QScreenUTS or QScreenT27 object the common
methods and properties are described in the superclass (QScreenTerm) from
which both are derived.
